PURPOSE: Choroidal detachment (CD) associated with rhegmatogenous retinal detachment (RRD) is a rare, but serious condition, which makes the prognosis worse. Previously reported risk factors for CD in RRD patients include high myopia, aphakia, pseudophakia, and advanced age. However, macular hole has not been discussed as an important factor in increasing the risk of CD in RRD patients. The purpose of this study was to evaluate macular hole as a risk factor for CD in eyes evidencing RRD. METHODS: The medical records of 480 patients with primary RRD were reviewed. We compared the CD incidence among the RRD patients in accordance with the presence or absence of macular holes. The relationship between gender, age, presence of systemic disease, refractive errors, lens status, intraocular pressure and the development of CD were also analyzed. RESULTS: The incidence (4/21 eyes, 19.0%) of CD in the RRD with macular hole was significantly higher than that (7/459 eyes, 1.5%) observed in the RRD without macular hole (p=0.010). The preoperative intraocular pressure (mean+/-SD; 2.5+/-1.3 mmHg) in the RRD with CD and macular hole was significantly lower than that (7.4+/-4.4 mmHg) observed in the cases of RRD with CD without macular hole (p=0.035). The eyes complicated by CD evidenced a higher prevalence of diabetes mellitus (p=0.024) than was observed in the eyes without CD. CONCLUSIONS: The retinal detachment combined with macular hole creates a predisposition toward the development of profound hypotony and CD.

PURPOSE: To evaluate the efficacy of excision of avascular bleb and advancement of adjacent conjunctiva (EBAC) for treatment of hypotony after trabeculectomy with mitomycin C (MMC). METHODS: Fifteen patients (17 eyes) who received EBAC for correction of hypotony between September 1996 and October 2008 were reviewed retrospectively. The main outcomes were intraocular pressure (IOP) and postoperative complications. RESULTS: Hypotony (IOP <6 mmHg) of eight eyes (47.1%, seven patients) was caused by bleb perforation. Of these, two eyes (two patients) had a history of trauma. Hypotony appeared at 33.9+/-30.8 months, and EBAC was performed at 48.2+/-35.3 months after trabeculectomy with MMC. The mean follow-up period was 38.3+/-29.8 months. The qualified success rate of EBAC was 100% at 51 months after EBAC, and the complete success rate of EBAC was 76.5% at six months and 70.6% at 51 months, as determined by Kaplan-Meier analysis. Post-EBAC complications included blepharoptosis in four eyes (23.5%) and bleb perforation in one (5.9%). The blepharoptosis resolved within one month after EBAC in two patients. However, in the other patients, mild blepharoptosis remained at 17 and 22 months postoperatively. CONCLUSIONS: EBAC was found to be an effective method for treatment of hypotony after trabeculectomy with MMC, and postoperative blepharoptosis was a major complication.
